a -citizen of the United S tates,lresiding` at Youngstown, in the countyof Mahoning il and AState of Ohio, have invented vcertain new and'useful Improvements in Bathing Material, -0f which 'the following is aSpeciication. f l i This Vinvention relates to a newcom-A positebuilding material .to be used chiefiyas athing in the construction ofwalls, oors, partitions and other structural parts.

VAnother object of the invention is to'make a newlathing vmaterial which yinherently will rfirmly and evenly maintain itsVform, '-85 and contribute to the strength and stability of the buildingstructure.l Furthermore,to
